Search for RPV SUSY resonant second generation slepton production in same-sign dimuon events at sqrt(s) = 7 TeV

A search for resonant production of second generation sleptons ($\tilde{\mu}$, $\tilde{\nu}_{\mu}$) via the R-parity violating coupling $\lambda'_{211}$, with two same-sign muons and at least two jets in the final state is performed. While one muon is expected to be produced directly in the slepton decay, the second muon and at least two jets are produced in the subsequent decay of a neutralino or chargino originating from the resonant slepton. The analysis is based on the 2011 dataset of proton proton collisions at a centre of mass energy of $\sqrt{s}=7$ TeV taken with the CMS detector, corresponding to an integrated luminosity of 4.98 fb$^{-1}$. The observation is in agreement with the expectation from Standard Model processes. Limits are set within the mSUGRA framework on the coupling $\lambda'_{211}$ in the range of scalar masses $m_0$ up to 1.3 TeV and gaugino masses $m_{1/2}$ up to 1 TeV and interpreted in the $m_{\tilde{\mu}}$, $m_{\tilde{\chi}_1^0}$ mass plane.
